Explanation:
Specific cutting energy:
It the ratio of power required to cut the material to metal removal rate of material.If we take the force required to cut the material is F and velocity of cutting tool is V then cutting power will be the product of force and the cutting tool velocity.
Power P = F x V
Lets take the metal removal rate =MRR
Then the specific energy will be
If we consider that metal removal rate and cutting tool velocity is constant then when we increases the cutting force then specific energy will also increase.
To solve this problem we will use the Froude number that relates the Forces of Inertia with the Forces of Gravity. There will be jump in the downstream only if Froude Number (Fr) is greater than 1 at upstream. Our values are given as,
Then the velocity would be:
The number of Froude is given as,
Where,
V = Velocity
g = Gravity
D = Diameter
Replacing we have that
There will be no Jump, correct answer is B.
Answer:
Number of Trays = Six (6)
Explanation:
Given that: y' = 25x' , in terms of molecular ratio, we can write it as
......... 1
after plotting this we get equilibrium curve as shown in the attached picture.
inlet concentration and outlet concentration of liquid phase is
x₂ = 4% = 0.04 (inlet)
so that can be converted into molar
and
x₁ = 0.2% = 0.002
Now we have to use the balance equation a
.............. a
here amount of solute is comparably lower than
Here we have
L = 300 kmol (total)
= 300(1 - 0.04) = 288 kmol pure oil
G = = 11.42 kmol
= 0 , solvent free steam
substitute into the equation a
Y₂ = 1.0003
Now plot the point A(X₁ , Y₁) and B(X₂ , Y₂) and join them to construct operating line AB.
Starting from point B, stretch horizontal line up to equilibrium curve and from there again go down to operating line as shown in the picture attached. This procedure give one count of tray and continue the same procedure up to end of operating.
at last count, the number of stage, gives 6.
∴ <em>Number of trays = 6</em>
